lwtunnel: valid encap attr check should return 0 when lwtunnel is disabled
An error was reported upgrading to 4.9.8:
root@Typhoon:~# ip route add default table 210 nexthop dev eth0 via 10.68.64.1
weight 1 nexthop dev eth0 via 10.68.64.2 weight 1
RTNETLINK answers: Operation not supported
The problem occurs when CONFIG_LWTUNNEL is not enabled and a multipath
route is submitted.
The point of lwtunnel_valid_encap_type_attr is catch modules that
need to be loaded before any references are taken with rntl held. With
CONFIG_LWTUNNEL disabled, there will be no modules to load so the
lwtunnel_valid_encap_type_attr stub should just return 0.
